Final answer:
Flea larvae primarily feed on dried blood from adult fleas and a small amount of fur from the host.
Step-by-step explanation:
Flea Larvae's Food Source
The food of flea larvae is primarily dried blood from the adult fleas and a small amount of fur from the host. Flea larvae do not directly feed on blood they suck from the host. Instead, they consume flea dirt, which is made up of dried blood and other organic matter present on the host's fur.
Example:
When adult fleas bite the host, they leave behind small amounts of blood on the fur. The flea larvae then feed on this dried blood and other debris, including fur, in their environment.
